a7147c1ffd ENT-4652: Provide an "attachment fixup" mechanism to repair broken transactions. (#5825)
* Do not register cordapp custom serialisers when using attachment classloader.

* Record the URLs of CorDapp JARs that contain custom serialisers. Include these JARs as extra attachments if we discover that we're missing a custom serialiser during transaction verification.

* Check for disabled serializer when explicitly requesting a custom serializer.
Refactor test case to force use of a custom serializer.

* Tidy up basic custom serializer test.

* Also test that TransactionBuilder rejects missing custom serializers.

* Remove test whitelists, which should not be needed with custom serialisers.

* Add changelog entry. Also align TestCordappImpl.findRoots() with OS backports.

* Second approach based around CorDapps inside AttachmentStorage - report missing type descriptor or any non-composable types.

* Initial implementation of Corda-Fixup rules inside a CorDapp jar.

* Replace original "automatic attachment fixing" mechanism completely.

* First review comments: restore "missing class" logic to TransactionBuilder.

* Restore "missing class" mechanism as fallback for SignedTransaction too.

* CORDA-3471: More changes after discussion with  @mnesbit
- Rename `VaultTransaction` into `SessionScope`.

* CORDA-3471: Revert changes to most of the files after conversation with @mnesbit and @rick-r3

c882b221a5 CORDA-3307 - add support for environment variables in linux (#5523)
* Added a new way for environment variables to be loaded, which allows for underscore based separation.

* Moved test to its own kotlin file.

* Added case insensitivity support.

* The corda. prefix is now case insensitive too.

* Removed unused variable.

* Added env variables support for driverDSL. Shadowing corda. properties raises an exception.

* Driver api stability fix.

* Changed type of cordapps param to reflect the real one, rather than what IntelliJ auto completed.

* Some detekt issue fixes. Spread operator removed, baselined api stability constructors and buggy line.

* Fixed misspelled variable.

* Reverted unintentional changes.

* Added suppress instead of changing baseline.

* Reworked logic to handle previously defined CORDA_ starting properties and handle accordingly. Fixed a bug where wrong class was used for reflection walking.

* Fix for detekt issues.

* Changed message to a more understandable one.

* Changelog + doc note, console error grammar.

* Changes according to PR review.

CORDA-3124: Ensure transaction is fully verified before sending to notary (#5516)
NotaryFlow.Client flow assumes the passed transaction is verified, which is
the case when it's invoked as a sub-flow in FinalityFlow. However,
NotaryFlow.Client can also be called directly from any custom flow, so
we need to ensure it performs transaction verification to avoid accidentally
sending an invalid transaction to a non-validating notary.

74e8b6e468 CORDA-3220: Updating FinalityFlow with functionality to specify StatesToRecord (#5482)
Updating FinalityFlow with functionality to allow the initiator to indicate the appropriate StatesToRecord. This allows the initiating party to record states in transactions which they are proposing but are not necessarily participants of. An example would be the issuance of a token where the only participant is the holder NOT the issuer.

* CORDA-3133 [v1]
This proposal is a little more flexible by design. It adds a property to the state pointer class, allowing them to be referenced in transactions on a per-state-pointer basis.

* CORDA-3133
 - Updated `resolveAtTransaction` to `isResolved`.
 - Moved `isResolved` out of the constructor into an abstract property.
 - Added deprecation constructor declaration for backwards compatibility.

* CORDA-3133 (version 2)
 - Added required changes to state pointers as per PR comments.
 - Added unit tests to ensure isResolved can be used to configure when state pointers should be resolved to reference inputs.

* CORDA-3133 (version 2)
 - fixed unit tests.
 - added comment to changelog.rst.
 - added helper functions to `StatePointer` to allow easier creation of static and linear pointers.

4cbe22949d CORDA-3018 Whitelisting attachments by public key - phase two tooling (#5386)
Allow node operators to blacklist signing keys (using blacklistedAttachmentSigningKeys config option). These blacklisted keys prevent attachments that are received over the network from being trusted. The docs have been updated to detail how to generate the key hashes that the config requires.

A new shell command attachments trustRoots has been added to see what attachments exist on the node along with information about their trust and where it comes from.

run dumpCheckpoints has been replaced by checkpoints dump as InternalCordaRPCOps needed to change to prevent a function that is meant to be internal from being visible on the shell.

When set to true the RPC client will:

* automatically reconnect when the connection is broken
* simple RPC calls will block until connection is established
* Observables returned from RPC will automatically resubscribe on reconnect so the client continues to receive events. This doesn't guarantee that events will not be lost during the reconnect.

ENT-3496: dumpCheckpoints shell command (#5171)
Dumps all the node's checkpoints as JSON into a single zip file in the node's directory. The output contains:

* All the fields for the top-level flow
* The current sub-flow call stack, along with the current progress tracker step for each sub-flow
* The event that suspended the flow, which if it's a send or sendAndReceive will show the payload that was sent
* Low level information on the active sessions with other peers
